Installation
5.13.9 Duration of ignition transformer discharge
The spark ignition is present during all safety time.
5.13.10 Reset by button and remotely of the burner
The burner can be released by pressing, for at least 0.4 seconds,
the reset button integrated in the control box and the unlocking
occurs only when the button is released.
The burner can also be reset using an external button (remote re-
set) connected to the R terminals (see RS electric diagram) on
the burner pressing for at least 0.8 seconds.
5.13.11 Protection reset
The burner can be reset only 5 times consecutively, then power
supply has to be disconnected for a new 5 reset possibilities.
The burner can only be reset if power supply is applied to the con-
trol box.
5.13.12 Reset push-button anomaly
If the reset button is faulty or is kept pressed for more than 60
seconds, the fault is indicated by the blinking of the LED (see par-
agraph
“Fault diagnostics - lockouts”
on page 24) as long as
it is present.
This fault is merely a visualisation.
If the fault is detected during pre-purging or safety time, the
burner does not stop (the start-up sequence will continue).
If the fault is detected during operation, the burner does
stops and stays stopped with the fault signal active.
If the fault is detected during a lockout, the fault is not sig-
nalled and the burner cannot be reset.
When the fault disappears, the LED stops blinking.
5.13.13 External lockout signal (S3)
The burner is equipped with an external locking signal function,
i.e. to signal (together with the integrated reset button) a burner
locking alarm.
The control box provides a command of an external lamp using
the S3 output (230Vac-0.5Amp max).
5.13.14 Hour counter functioning (B4)
The burner has an hour counter function that is active as long as
the 1st stage oil valve is open and therefore as long as fuel is be-
ing consumed.
The control box provides an external meter through the
Hour_Counter output (230V AC-0.1Amp max.) of the control box
connected to pin B4.
5.13.15 Monitoring the power supply voltage
The control box automatically measures the mains voltage.
If the voltage is less than 160V or more than 280V, the burner
stops, interrupts the operating cycle and remains in stand-by, sig-
nalling a fault. The fault is indicated by way of the blinking LED
(see paragraph
“Fault diagnostics - lockouts”
The burner restarts when the voltage is exceeds approx. 170V or
is brought back under 270V.
If the fault is detected with flame operation, the valve is imme-
diately closed and the motor stops.
If the anomaly is detected during pre-purging, the motor
stops.
If when the main power supply switch is closed or after there
has been no power, the mains voltage stays within the inter-
mediate values (160-170V or 270-280V) the burner does not
start.
If the burner is in lockout, the mains voltage is monitored but
is not signalled in that there is a lockout signal.
During the ignition time the mains voltage monitoring is deactivat-
ed.
5.13.16 Frequency supply error
The control box automatically detects the value of the frequency
of the main supply in the range of 50 - 60 Hz, in both cases work-
ing times are verified. The fault is indicated by way of the blinking
LED (see paragraph
“Fault diagnostics - lockouts”
page 24).
If the anomaly is detected before heat demand the burner
does not start.
If the fault is detected during the pre-purging, the burner
remains in purge condition and the fault is appropriately sig-
nalled.
The fault is not detected during normal running, the burner
remains in this state.
When the fault disappears, the burner restarts.
5.13.17 Internal voltage anomaly
The control box automatically detects if the internal voltage works
correctly. The fault is indicated by way of the blinking LED (see
paragraph
“Fault diagnostics - lockouts”
If the anomaly is detected during the initialisation check time,
the burner does not start.
If the anomaly is detected after a lockout the burner does not
start.
If the anomaly is detected after a shut-down test, the burner
does not start.
The fault is not detected during normal running, the burner
remains in this state.
When the fault disappears, the burner restarts.
5.13.18 Checking the fan motor
The control box automatically detects the presence of the fan mo-
tor and, in the event of a fault, it performs a lockout. The lockout
is indicated by the blinking of the LED (see paragraph
WARNING
In the event of continuous recycling or heat re-
quests that are close together, the maximum al-
lowed number of cycle repetitions for the ignition
transformer is one every minute.
WARNING
If the reset button is pressed for more than 2 sec-
onds, the control box goes into visual diagnostic
mode and the indicator LED begins to blink (see
‘Fault diagnostics - lockouts” a pag. 24).
